(A) DEP-FFF fractogram for separating MDA-435 cells from CD34+ cells by the swept-frequency protocol. (B) Corresponding contour plot for fluorescence level vs. elution time for cells that exited the DEP-FFF chamber. The DEP field was swept between 15 and 35 kHz for 7 min and then switched to 5 kHz for 7 min. DEP signal voltage and fluid-flow conditions were the same as those used in Figure 2.
